Review on 🔆 Glarks 2PCS Blue Solar Panel Tool for Easy Assembly and Disassembly, with 5 Pair Male/Female Connectors Set for Roof Mounted Solar Panel on Motorhome, RV, or Camper by Robert Farrar

MC 4 required to connect the solar panel flex wires on my RV to the charge controller wiring. The 2 keys provided were definitely a plus! Please note that they do not come with instructions - you either need to know the MC 4 and know how to assemble it, or be able to figure it out! The internal metal connectors are best soldered, but since I've been working I just crimped them onto the cable and it seems to work fine. They fit right in with the MC 4s that were already attached to the panel pins.
